ROTARY ENGINE-VALVE.

To all whom it may concern:

Be it known that I, Vrc'ron H. ANDERSON, a citizen of'the UnitedStates,.residing at Mount Vernon, in the county of Kennebec 5 and Stateof Maine, have invented new and useful Improvements in Rotary 'Engine-Valves, of which the following is a specification.

This invention relates to rotary valves for internal combustion enginesof the multiple cylinder type, the object in view bein to roduce a valveof the'class specified w ich is adapted to take care of the lntake andexhaust of a multiple cylinder engine each cylinder of which onlyrequires a single port to take care of both the intake and exhaust ofthe fresh mixture and burned gasesL.

One of the chief object's of the present invention is to produce a valveof the character stated in which there are self-contained intake andexhaust manifolds, whereby the inflowing cool mixture will be heated bythe burned gases upon their movement through the valve to the exhaustchamber.

A further object of the invention is to produce a valveof the classabove defined, the construction of whic renders it reliable andefficient, enables the same to be lubricated without permitting thelubricant to enter the engine, which effectively excludes foreign.matter, and which may be driven with a very small percentage of power ofWitE the above and other objects in view, the invention consists in thenovel construction, combination and arrangement of parts, as hereindescribed, illustrated and claimed.

In the accompanying drawings: Figure l is a cross section through amultiple cylinder engine embodying the present invention. Fig. 2 is ahoriz ntal section on the line' 22'of Fig. 1. 3 is a plan view of theinner portion of'the valve including the valve shaft, the manifoldforming partition, and other parts intimately associated with the valveshaft. Figs. 4:, 5 and 6 are,

respectively, sections on the lines H, 55 and 6-6 of Fig-:2, omittingall parts except the valve itself. Fig; 7 is a section on the I 8 is adetail view 3 one of the rings.

Specification of.Letters fatent.

. shown, the cylinders A and B, four in number, are arranged at an acuteangle to each other but it will of course be understood that the anglebetween the cylinders Aand B maiy be varied to suit the will of the manuacturer and that, if desired,- the said cylinders A and B may bearranged ver tlcally or in parallel relation to each other.

The main feature of the invention resides.

in the valve which is designated enerally at D, the same comprising acentre? and an outer cylindrical tubular shell 2, the medial portion 3and'the extreme end porshaft'l,

tions 4 of which are shown as imperforate.

The portions5'and f5 lying at opposite sides of the medial portion 3 areprovided each -with an inlet port and an exhaust port, the

portion 5 at one side comprising the inlet ported portion at theopposite side of the imperforate medial portion 3 is formed with aninlet port 9 and an exhaust port 10. In

-cycle engine and therefore revolves at one half the speed of the engineshaft, the intake .and exhaust ports at one side of the central portion3 are arranged substantially at ninety degrees apart so that theexhaust.

stroke will be followed by the intake stroke,

lport 7and the exhaust port 8, while the-' the remainder of the shell inline with said ports being imperforate for approximately one hundred andeighty degrees so as tof'provide for the compression and firing strokes.

Furthermore, the ports 9 and "10, collectively, are arranged ninetydegrees from the ports? and 8 so that the explosions in the fourcylinders will follow each other successively. designates a manifoldforming Pattisimilar semi-circular end wall 13 which closes one half ofthat end of the cylinder. Between its ends, the partition or Web 11 isgiven a quarter twist at 14, said twisted portion of the partition orweb lying Within the imperforate medial portion 3 the shell 2 Thisquarter twist of the web or partition 11 is required in order to receiveand deliver the fresh mixture'to thecylinders and also to receive anddischarge the burned gases therefrom. The shell 2 is supported by meansof the end walls 12 and 13 and the outer edges of'the partition or web11 including the angular or twisted portions 14; thereof.

The shaft 1 is .journaled in bearing memhers l5 and 16 and is providedat one end with a squared or non-circular portion 17 on which is mounteda silent chain wheel 18 from which a silent driving'chain extends to thecrank shaft of the engine. On the same squared portion 17 of the shaftis mounted a fan belt pulley 19 held in place' by a nut 20. The wheel 18is formed with anextended hub 21 forming another-jean nal which ismounted in a bearing member 22, the bearing members 15, 16 and 22forming parts of the engine frame. At the opposite end the shaft 1 hasfast thereon a silent chain wheel 23 from whiclra chain extends to themagneto shaft. .Keys 2 1 are employed'to securely lock the wheels 18 and23 to the shaft 1. The shaft 1 is further provided with flanges orcollars 25 and 26 beyond the ends of the valve, said collars workingagainst the adjacent end walls of the valve chamber so as to preventleakage of mixture or burned gases from the valve chamber at said pointsand also to prevent the oil from the journals 15 and 16 from enteringthe intake chamber 27 and the exhaust chamber 28 to which are connectedsuitable intake and exhaust pipes as may be found convenient.

Oil is introduced through an opening 29 into a groove 30 in the insideof the valve chamber wall where it enters an annular series of oilgrooves 31 inthe outer face of the .imperforate medial portion 3 of theshell, the oil being conducted through the grooves 31 to other grooves32 and 33 in a pair of skeleton shaped packing rings surrounding theported portions 5 and 6 of the valve shell so as to produce a snug fitbetween the valve and its containing casing, preventing the lubricatingoil from reach ing the intake and exhaust ports and also preventingleakage of the mixture and er;- haust gases at such points. y

In operation, it will be understood the valve as a Whole herciuabovedescribed may be operated or revolved at one half the veryv smallpercentage of the engine power. The timing of the intake and exhaust isfixed and therefore invariable so that the very best results may beobtained as regards the power and general efficiency of the ensmooth inits operation. The inlet and exhaust manifolds are selfcontained withinvthe shell'of the valve and thus the incoming mixture is heated. by theexhaust, producing at all times a good explosive mixture, resulting inbetter combustion, increased power and reduction in the accumulation ofcarbon in'the engine cylinders and on the heads of the pistons. It willbe observed that there is only one port in each cylinder, which porttakes care of both the inlet of the charges and the exhaust of the,

burned gases. Under the arrangement of the valve in its relation to theengine cylinders hereinabove described, the valve itself is protectedfrom the highest temperatures which occur withinthe cylinders at thetime the explosions take place. Having thus described my invention, 3:claim 1. In a multiple cylinder ll-type internal combustion engine, thecombination of gularlv related cylinders, a valve chamber locatedbetween the angularly related cylinders and formed with acylindricalbore and a single port for each cylinder acting both as an intake andexhaust port, a rotary cylindrical valve mounted to revolve in saidchamber and embodying a tubular shell having an imperforate medialportion and ported portions at opposite sides of said medial portion,each formed with an inlet port and an exhaust port which successivelyregister with the ports of the said cylinders, an intake chamber at oneend of said valve, an'exhaust chamber at the other end of said valve,and an internal partition ex tending longitudinally" and diametricallyof said shelland shaft and forming valve-contained intake and exhaustmanifolds.

2. In a multiple cylinder ll-type internal combustion engine, thecombination of angular-1y related cylinders, a valve chamber locatedbetween said angular-1y related cylinders and formed with a cylindricalbore and a single port for each cylinder acting both as an intake andexhaust port, a rotary cylindrical valve mounted to revolve speed of theengine shaft, requiring but a. v

. gine. Furthermore, the valve is silent and in said chamber andembodying a tubular shell having an imperforate medial portion andported portions at opposite sides of said medial portion, each formedwith an inlet port and an exhaust port which successively register withthe ports of the respective cylinder, and an internal partitionextending longitudinally and diametrically of said shell and foi-mingValve-contained intake I and exhaust manifolds.

In testimony whereof I aflix my signature in presence of two witnesses.
